BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Scales on back and sides densely covered with slender bristle-like spines, which are arranged 
in numerous parallel series somewhat difficult to determine; on head the spines are much coarser 
and less numerous, and the series strongly radiate; mandibles, gill-membranes, and the space below 
suborbitals and rostral ridge naked, the rest of head completely invested; lateral line prominent and 
continuous, describing a low curve above pectoral fin. 
Color light grayish, cheeks and opercles not darker than sides of body; under side of snout, lips, 
and mandibles blackish, more or less mottled with silvery; gill-membranes purplish black, breast and 
abdomen dusky; mouth and gill-cavities whitish, lining of abdominal cavity bright silvery, with 
scattered black specks; membrane of first dorsal silvery with scattered black specks, a few small dark 
spots on the rays; anal whitish, blackish at base of the anterior 12 rays; pectorals and ventrals dusky, 
the latter with silvery pigment; ventral filament white. 
One specimen only. 
Named for Lieut. G. H. Burrage, U. S. Navy, navigating and executive officer of the Albatross, to 
whose efforts was directly due much of the success of the expedition. 
Macrourus obliquatus, new species. Fig. 261. 
Type, 165 mm. long, from station 4141, off the east coast of Kauai, depth 437 to 632 fathoms; type, 
No. 51514, U. S. Nat. Mus. 
Body very long and slender, depth at origin of dorsal contained 1.6 times in head. First dorsal ii, 
11; V. 12; P. 22 or 23; scales between lateral line and base of second dorsal spine 9. 
Head rather long, with moderately projecting snout, and narrow inferior mouth, which is much 
overpassed by the snout anteriorly and by the infraorbital ridges laterally; length of snout slightly 
exceeding vertical diameter Of orbit, contained 3.6 times in length of head, its preoral length 0.3 
Pis. 261 .— Macrourus obliquatus Gilbert, new species. Type. 
length of head behind snout; snout terminating in a very spinous tubercle directed very obliquely 
upward; a pair of prominences also on side of snout where each infraorbital ridge joins the ridge which 
bounds the upper portion of the nasal fossa; from the median tubercle a ridge extends backward nearly 
to middle of interorbital space, the latter deeply concave; from the supraorbital rim a pair of curved 
ridges converge backward toward occiput; width of interorbital space equal to 0.7 the long diameter 
of orbit, which is oblique downward and backward, and equal to 0.3 length of head; front of mouth 
slightly in advance of nostrils; tip of maxillary scarcely reaching vertical from hinder edge of pupil, 
its length equaling 0.3 that of head; greatest width of mouth contained 1.7 times in its length; behind 
angle of mouth, on outer mandibular rim, a short strong compressed spine directed backward; teeth 
in rather wide villiform bands in both jaws, 12 or 14 of the outer series in the front of upper jaw, at 
least twice the size of the villiform teeth behind them; cheek produced downward and backward into 
a narrow rounded lobe encroaching on preopercle; preopercular margin not produced, its vertical
